This is some data that is about 18 months old that needed to be looked at again, so here we have it!
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus. The remarkable shape of the emission nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen. The distance of the nebula complex is though to be approx 1800 light years away.
This is a total exposure time of 29 hours and 30 minutes, all exposures being 30 minutes long. It's made up of a 2x2 pane mosaic.
